The MIPS architecture supports byte and halfword (16-bit) memory transfer operations. The instructions are load byte (Ib), load byte unsigned (Ibu), store byte (sb), load halfword (lh), load halfword unsigned (lhu) and store halfword (sh). Code: short int a, bi //16-bit variables (a address 100) (b @ address 200) Part a) Assuming 16-bit operations are supported (lh, lhu, sh), write a MIPS code that swaps the variables a and b. Part b) IfMIPS doesn't support byte and halfword operations, then we can access the memory using the load word' (lw) and 'store word' (sw) only, which are 32-bit operations. Accordingly, rewrite the code above using only (Iw, sw) to access the memory. You can use other logic/arithmetic/branch instructions
